Michigan will be without one of its offensive standouts when it begins spring practice. The Wolverines announced on Thursday that rising sophomore tight end Jake Butt suffered a torn ACL in winter workouts. He is out indefinitely.

In a statement, Michigan coach Brady Hoke said that Butt's injury is a blow to the offense.

"Jake's done a tremendous job since he's been here," said head coach Brady Hoke. "He's worked extremely hard and gained a lot of weight to become the complete tight end he wants to be. I think he showed flashes of that towards the end of last season. This is a tough break, but because of his work ethic and attitude, the kind of young man he is, we know he will be back as soon as he can and as strong as ever."

As a freshman in 2013, Butt ranked third on the team in catches (20), receiving yards (235) and receiving touchdowns (2). His best performance came in the regular-season finale against Ohio State, when he caught five passes for 85 yards and a score in a 42-41 loss.
